Description

The Start Multiple EC2 Instances action can be used to start many EC2 instances at a specific time of day. Once the instances have been started, they can optionally be stopped after they have been running for a specific amount of time.

For example, 5 instances can be started at 8am and stopped 8 hours later with a single Start Multiple Instances action.
